• Splitting the feed water to a pressure vessel utilizing a center port

• Reduces the hydraulic pressure drop through a shorter flow path of membranes

• Reduces feed pumping energy consumption for energy savings 35-40% over conventional Nanofiltration

• Feed pressure reduced from 90-100psi to 53-55psi

• Cost approximately 15% increase over conventional design

• Payback period less than 3 years based upon known electrical data

• $1.45M present worth estimated energy savings for 20 years for 14.5 MGD facility

• 85% recovery and average flux of 15 gal per sq ft per day. No rapid fouling or scaling issues.
